Description

[Detailed explanation of the invention] In addition to the functions of the musical instrument itself, this invention allows accessories such as a rhythm generator, synthesizer, and cassette to be attached to the main body of the musical instrument in order to generate sound effects and improve the learning effect of the musical instrument. Regarding equipment.

Conventionally, for example, in an electronic organ or an electric piano, in order to improve the above-mentioned functions, an accessory _C1 is placed on the top plate b of the main body a of the musical instrument as shown in the first figure, or a shelf board on which the keyboard is placed is placed. Another accessory, _C2 , was screwed to the bottom of d, but the former was difficult to operate, and the latter had the inconvenience of clumping when not in use.

The present invention eliminates such inconveniences and provides an accessory that does not generate noise due to the vibration of the instrument body, allows smooth movement of accessories, and whose position is stable against the vibrations when in use and when not in use. The purpose of this device is to provide a device for attaching accessories, in which an accessory case support is attached to the instrument body via an elastic body, and a rotating body having a flange is pivotally supported, and rails are provided on both sides of the accessory case. are fitted to the rotating body, and when the accessory case is stored in the instrument body and pulled out, the locking notch provided in the rail is engaged with the flange of the rotating body. .

Embodiments of the present invention will be described below with reference to the drawings.

The accessory case 1 for storing accessories or for the accessories themselves has a rail 1b fixed to both side walls 1a by spot welding or the like, as shown in the second figure, and both upright sections at the middle of the rail 1b A lock notch 1c was provided in the wall, and a stopper screw 1d was screwed into the rear end. On the other hand, the accessory case support 2 is attached to the instrument body 3 as shown in FIGS. 3 and 4.
Horizontal plate part 2a provided with screw holes 4 for attachment to
and a flange 6a via an elastic body 5 such as a sponge.
An upright plate portion 2 that pivotally supports a rotating body 6 with screws 7.
Consists of b. A rotary body 6 pivotally supported by the accessory case support 2 is rotatably fitted into a groove in the rail 1b of the accessory case 1, and the flange 6
A was brought into pressure contact with the end of the upright wall of the rail 1b by the elastic force of the elastic body 5.

Thus, when the accessory is not in use, the locking notch 1c of the rail 1b of the accessory case 1 is pivotally supported by the accessory case support 2 by the elastic force of the elastic body 5, as shown in FIG. It engages with the flange 6a of the rotating body 6.

Therefore, even if the musical instrument main body 3 vibrates, the stored accessory case 1 will not come out from the musical instrument main body 3 due to the vibration. Next, when pulling out the accessory case 1 to use the accessory, the rail 1
The locking notch 1c of b disengages from the flange 6a of the rotating body 6 against the elastic force of the elastic body 5,
The rail 1b moves forward while rotating the rotating body 6. When the accessory case 1 is pulled out to the position where the accessory is in use, that is, until the rear rotating body 6 hits the stopper screw 1d, the locking notch 1c of the rail 1b is inserted into the front rotating body 6.
flange 6a. Therefore, even if the musical instrument body 3 vibrates or receives an impact while the accessory is in use, the accessory case 1 will not be drawn into the interior of the musical instrument body 3. In the process of pulling out the accessory case 1 to the position in use, the edges of both upright walls of the rail 1b are in contact with the flange 6a of the rotating body 6, so that no noise is generated.

In this way, according to the present invention, the rotating body 6 having the flange 6a is attached to the musical instrument body 3 via the elastic body 5.
When the accessory case 1 which is pivotally supported is attached, the rotating body 6 is fitted into the rails 1b provided on both sides of the accessory case 1, and the accessory case 1 is stored in the instrument body 3 and pulled out, The locking notch 1c provided in the rail 1b is inserted into the flange 6 of the rotating body 6.
Since it is engaged with the main body 4 of the keyboard instrument, the accessories such as a rhythm generator do not get in the way when they are not in use, and their position is locked when they are in use and when they are not in use. The accessory case 2 does not move due to vibration, and the accessory case 2 can be moved smoothly and there is no noise during movement.
